What Are Waves?

Waves that require a medium to travel through are _____________

• Mechanical
• Electromagnetic
• Water
• Sound

Which is the best description of a vibration?

• When a rope moves up and down
• When energy is transferred from one object to another
• when there is a repeated back-and-forth motion resulting from energy
• the transfer of energy that is immediately stopped in the medium

The type of wave is classified by how it moves through a medium.

• True
• False

A wave that vibrates the medium perpendicular to the direction of the wave is

• Parallel
• Transverse
• Longitudinal
• Surface

The high and low points on a transverse wave are called the

• trough and node
• node and trough
• crest and trough
• amplitude and trough

According to the picture, what would best describe rarefaction?

• the areas where the particles are pressed together more
• areas that would be the "crest" of a transverse wave
• the areas of the wave that have more spaced out particles of the medium
• the areas where the wave is crossing over the line of rest

What type of wave is seen in the picture?

• Longitudinal, Compressional
• Transverse, Compressional
• Compressional, Surface
• Electromagnetic, Surface

A wave is a disturbance involving the transfer of energy from place to place.

• True
• False

What does a wave transfer?

• matter

• energy

• power

• water

Which type of wave has rarefactions and compressions?

• transverse

• longitudinal

• electromagnetic
